使用helm push操作harbor charts仓库

当harbor升级到2.1之后，很多技巧就可以玩起来了哈，先来helm charts的管理。下一篇是ormb作AI模型管理。

一，helm增加helm push插件

• 如果可以连网
  helm plugin install https://github.com/chartmuseum/helm-pus
• 如果不能连网
  helm plugin install helm-push_0.9.0_linux_amd64.tar.gz
• 或是直接把helm-push_0.9.0_linux_amd64.tar.gz里的文件cp到$HELM_PLUGINS目录(此目录可以通过helm env命令获得)。
  二，helm 增加harbor repo
  helm repo add harbor-test-helm-repo --username=xxx --password=xxx http://harbor-test.demo.com.cn:8086/chartrepo/helm-repo
  查看已有的repo
  helm repo list

NAME                    URL                                                             
harbor-test-helm        http://harbor.demo.com.cn:8086/chartrepo          
harbor-test-helm-repo   http://harbor-test.demo.com.cn:8086/chartrepo/helm-repo
harbor-test-helm_repo   http://harbor-test.demo.com.cn:8086/chartrepo/helm_repo

三，helm搜索harbor里的charts

• 先更新本地charts缓存内容
  helm repo update

Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "harbor-test-helm_repo" chart repository
...Successfully got an update from the "harbor-test-helm" chart repository
...Successfully got an update from the "harbor-test-helm-repo" chart repository
Update Complete. ⎈Happy Helming!⎈

• 在harbor repo时模糊搜索指定charts
  helm search repo seldon
• 输出近似内容

NAME                                            CHART VERSION   APP VERSION     DESCRIPTION

harbor-test-helm_repo/seldon-mab                0.2.0                           Chart to deploy a multi-armed bandits router ov...

四，helm push，将本地charts加入harbor charts

• 一种方式是直接上传charts文件夹
  helm push seldon-mab harbor-test-helm
  seldon-mab是charts目录
  harbor-test-helm是harbor charts repo名称。
• 另一种是将charts package文件包push
  helm push seldon-core-operator-1.5.1.tgz harbor-test-helm
  这两种方式输出都类似：

Pushing seldon-mab-0.2.0.tgz to harbor-test-helm...
Done.
Pushing seldon-core-operator-1.5.1.tgz to harbor-test-helm...
Done.

五，下载helm应用charts
helm pull harbor-test-helm-repo/seldon-mab

• harbor-test-helm-repo表示harbor chart repo
• seldon-mab表示这个repo里的具体的charts

此命令将会在当前目录下，生成一个seldon-mab-0.2.0.tgz文件。
(我怀疑helm pull生成的文件和helm package文件是一样的，一个从远程，一个从本地)

六，helm安装应用
也有两种方式

• 从远程harbor charts repo安装
  helm install seldon-mab harbor-test-helm-repo/seldon-mab
  seldon-mab这是命名，必须的，要不然要自动产生名字--generate-name
• 从本地目录或压缩文件安装
  helm install seldon-core-operator-1.5.1.tgz
  查看已安装charts
  helm list
  输出

NAME            NAMESPACE       REVISION        UPDATED                                 STATUS          CHART                APP VERSION
seldon-mab      default         1               2021-01-13 15:01:16.59675153 +0800 CST  deployed        seldon-mab-0.2.0                

七，删除helm charts应用
helm uninstall seldon-mab
seldon-mab即为charts name。如果有namespace，也需要加上。
